That is possible, of course. There just wasn't any market for such feature on the Amiga because of the dreaded 7 MHz 512KB base configuration.

A lot of Amiga demos use less than 256 colours for...

The required computing power for texture mapping doesn't really get less with less than 256 colours because you need to read the texel and then write it to the screen buffer. Since this is a chunky...

Worst was the Atari 2600 joystick which didn't last more than a few days. Best was Quickshot II (the microswitch version). In between the two is the Competition Pro. It's durable but not very...

Ah, yes, you are right, I now remember. But I believe that LEs are counted differently between the Cyclone III and V series and the 77k of the V are pretty much comparable to the 55k of the III but I...

For all I know the V1200 has the same larger FPGA as the V4 range. Only V500 and V600 have the smaller FPGA. But it was stated that development will happen on the basis of the V4 and some additional...

I don't know the tsunami, but 40ish MHz 030 certainly doesn't sound wrong. I used to love my Blizzard 1230 back in the day but given the choice between two 030 accelerators, I would choose the...

If you want power, get a Vampire. A 50 MHz 030 is perhaps something like 10 MIPS, a 56 MHz 030 is 11 MIPS. Wow, a whole 1 MIPS more for what, a 100€ extra?

A Vampire is 150 MIPS.

Actually we still have new WHDload bugfixes made and I would assume we would know about software breaking from more than 2MB chipmem present by now. UAE has offered this option for a long time now.

But then P96 will decide it won't use the blitter for anything above 2MB and use the CPU which in the case of a Vampire seems to be the better option anyway. Or am I missing anything?
